Another performance issue we've run into is the call to Strings.toClass(clsName, findDerivedLoader(conf, loader)) in Configurations.newInstance().
To work around the problem we tried caching the Class created for a given ClassLoader. It's a relatively simple cache, but it yielded noticeable performance improvements. The attached patch is relative to openjpa-lib, I can attach one that is relative to trunk if that will help.
